Certified Window System Engineer (NFRC) The NFRC recently overhauled its certification framework to emphasize dynamic performance metrics alongside traditional thermal ratings. Modern window systems now face stricter solar heat gain evaluations and condensation resistance thresholds, reflecting climate-adaptive building codes. Engineers must navigate updated calculation methodologies for non-homogeneous frames and updated field testing protocols that didn’t exist in prior versions.
